Application filed May 18, 1914. Serial No. 839,237.

ToaZZ whom it may concern Be it known that I, Aus'rrnG, HILL, a citizen of the United States, residing at Chelsea, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Toggles for Use in Stretching Leather, of which the following is a specification.

My invention relates to toggles such as are used in the manufacture of leather to fasten hides within stretching frames, and the object thereof is to provide an improved toggle of this kind.

My invention consists of a toggle for use in stretching hides embodying the novel features of construction set forth in the following description and particularly pointed out and defined in the claims at the close thereof.

In the accompanying drawings :Figure 1 is a perspective View of a toggle embodyin one form of my invention. Fig. 2 is a perspective view of the head ofthe toggle shown in Fig. 1. Fig. 3 is a section on line 3-3 of Fig. 1. Fig. 4 is a perspective view showing the manner in which my improved toggle is connected with a hide. Fig. 5 shows another form of head. Fig. 6 is a perspective view of a toggle embodying an other form of my invention.

The toggle shown in Figs.v 1 to 4: inclusive, comprises two non-metallic parts consisting of a head 10 preferably made from wood, and a cord or the like 11. The head 10 is preferably a rectangular bar of wood formed near one side with a longitudinal slot or cut 12 open at one end so as 'to provide a yielding cord clamping tongue 13 integral with a rigid body 141. The body 1 1 of head 10 is formed near its middle with a transverse groove 15, Fig. 2, across which the tongue 13 extends. In attaching the cord 11 the end 11 of the latter is slid sidewise into slot 12 until it occupies groove 15 and then the body portion 11 of the cord is wrapped once around both the tongue 13 and body 14: after which the opposite end 11 of the cord is also slid sidewise into slot 12 until it lies in groove 15 alongside of the first end. Then 1n position the cord is held against accidental displacement by the pressure of tongue 13. The end 11 in practice is made about eighteen inches long so that after the head end of the toggle has been attached to the edge of the hide as shown in Fig. 4, the end 11 can be attached to the stretching frame. In attaching the toggle to a hide a 1 hole 16 is made in the latter near its edge at the point where it is desiredto apply the toggle, and then the end 11 of the cord is passed through this hole, around the edge of the hide and head 10, and again through hole 16 after which it is pulled forcibly toward the frame and fastened to the latter in the customary manner. distinguishing feature of my improved toggle is that when the toggle is in use the strain on the cord 1111 acts to clamp the cord firmly and hold it against slipping relatively to the head. That is to say, I dispense with the metallic fastener which has heretofore been used to fasten the cord to the head and by the peculiar construction of head and peculiar application of the cord thereto, above described, make use of the strain on the cord to bind the cord to the head so that the two cannot pull apart while in use.

It is of considerable importance that the head 10 be made of wood or the like as described so that the trimmer can cut close to the toggle without danger of injury to his knife when removing the hide from the frame. Heretofore it has been the practice in making toggles with wooden heads to fasten the cord to the latter by means of a metallic staple driven into the head. The disadvantage to this method was that three parts were required and the wooden head was weakened transversely near its middle by the penetration of the staple. My invention obviates this objectionable feature, and provides a toggle made up of only two essential parts, the head being so constructed and the cord so applied that the head will stand more strain than wooden headed toggles as heretofore made.

The head shown in Fig. 5 is constructed the same as the head already described except that in the form shown in Fig. 5 the groove 15 is dispensed with and in place thereof the tongue 13 and body 14: are bored as at 17 to receive a plug of wood or the like which is inserted in said holes after the cord is applied and serves to hold said cord against slipping out of the slot 12.

In the form of my invention shown in Fig. 6 the head 18 is formed at each end with a V shaped recess 19'and the cord is wrapped lengthwise around the intermediate portion of the head, the tail end 11 lying under the long end 11 so that the strain on The peculiar andthe latter causes said end 11 to be clamped securely between long end 11 and the body of the head. A retaining pin 20 serves to hold the cord against becoming accidentally disconnected from the head during handling. The recesses 19 are made narrowest at their inner ends so that when the cord is forced into said recesses and more or less compressed it is also frictionally held against accidental displacement.

In another form of toggle heretofore used, the cord was merely knotted around the bar and was liable to come loose and also to cause damage by unequal stretching. Moreover the cost of making in this manner Was an item of consequence on account of the great number used and because of the fact that a toggle is only used once. This may be said also of other forms of toggles, such as those in which the cord is held firmly to the bar by staples or a pin. With my invention simplicity of construction and positive action are combined with economy of material and low cost of manufacture.

What I claim is:

l. A toggle for use in stretching hides and the like comprising a head formed with a cord recess and a cord having one end thereof arranged within said recess with the adjacent portion of said cord extending from said end around the exterior of said head and through said recess, so that the strain on the cord causes said adjacent portion alone to clamp and hold said end against slipping out of the recess when the toggle is In use.

2. A toggle for use in stretching hides and the like comprising a head and a cord, the head being formed with a longitudinal cord receiving slot near one side so as to provide a resilient tongue, and the cord extending through said slot and wound around the body and tongue of the head so that the strain on the cord while the toggle is in use acts through the tongue to clamp the cord against slipping.

3. A toggle for use in stretching hides and the like comprising a head of wood or the AUSTIN G. HILL.
